Cruise Control not working

[jvazquez53]

This is one of the "few" things that do not work on "El Tractor Dos", I noticed a couple of days ago. I looked at fuses, but they all seem Ok. Where should I look??

Also, search for how to test it in the vehicle. There are posts about it but I can't remember where. It can help you narrow down exactly what part is at fault.

Open up the cruise control box under the hood on the pass side and manually cycle the arm a few times.

If the dash BRAKE lamp is on, CC is deactivated.

The 2 things that illuminate the BRAKE lamp are the handbrake handle and the brake fluid reservior cap. If the cap switch fails it sometimes goes into a partial closure that will very dimly illuminate the lamp. So much so that you can't see it in daylight. This will deactivate CC as well.

Looks like I'll be busy this coming weekend. I just got the radio working... music!!!! I still have to tackle the power windows on the passenger side, they don't come down, more .

I hope it doesn't come down to this, but you might learn something here:

Cruise Control Actuator Service

BTW if you look through the pics you will understand why "cycling the lever" does very little to fix the basic problem, other than to make you feel good. The inside of the unit gets plugged up with hardened gloppy grease.

Several years after gutting my servo and reassembling it, my CC is still working flawlessly.

Good luck.

Mods - this write up belongs in the FAQ section if it already isn't there.

You have the FSM?

There's a very cool, very definitive diagnostics mode for the cruise control system. Allows you to pull codes (as with the CEL) and easily pinpoint the problem.

I'll check.

Hey John, what were the symptoms that led you to teardown the CC module?

Old thread I know. But this worked for me. Looks like it's time to service my actuator.

I posted about the Stop Lamp Switch being bad and how replacing it fixed my CC: 94 Cruise Control Problems - https://forum.ih8mud.com/threads/94-cruise-control-problems.371952/
